Transaxle Cooling
The transmission fluid cooling system consists of the following:
- OTA transmission fluid cooler
- A non-repairable in-tank transmission fluid cooler
- Front transmission fluid cooler tube assembly
- Rear transmission fluid cooler tube assembly
- Transmission mounted transmission fluid cooler outlet tube
- Transmission mounted transmission fluid cooler inlet tube
- Transmission fluid cooler bypass valve
- Transmission fluid cooler - warmer
These vehicles are equipped with an OTA transmission fluid cooler and an in-tank transmission fluid cooler. The transmission fluid cooling system also consists of a transmission fluid cooler - warmer assembly which has a transmission cooler bypass valve mounted to the top of the transmission fluid cooler - warmer. Transmission fluid travels from the transmission to the transmission fluid cooler - warmer. The transmission fluid cooler - warmer warms the transmission fluid to the transmission operating temperature using heated engine coolant. When the transmission fluid is at or above normal operating temperature, the transmission fluid cooler bypass valve opens allowing transmission fluid to travel from the transmission through the in-tank transmission fluid cooler then through the OTA transmission fluid cooler then back to the transmission. The transmission fluid cooler transfers heat from the transmission fluid to the outside air.
